Your first paragraph is correct, people can give however much they want to spend on political promotion, advertisement, etc. That's what a PAC is, groups that organize advertisement. You're still misrepresenting reality and when you say that this functions to "facilitate the flow of money from special interests into the pockets of politicians." This money never enters the pockets of politicians. If that happens, it is a violation of the law. Definitely certain PACs benefit certain politicians over others. A PAC organized to promote environmentalism is probably going to help Democrats a lot more than Republicans. But it is not correct in any way to say that this money is funneled to the politicians themselves. The politician does not hold the purse strings of PAC money, the PAC can decide at any time to stop promoting items aligned with that politician.
